scope:

IEC 62977-2-7 ED1 specifies standard measuring conditions and measurement methods for determining the optical characteristics of tiled displays which consist of multiple display modules in order to form one screen. These methods apply to emissive and transmissive direct view flat displays that render real 2D images with all modules lying in the same plane. The methods are applicable in environments where the measuring conditions can be controlled, such as laboratory and production testing. NOTE The measurement results are not specific values for the products. They can vary according to the measurement method and light measuring device (LMD) used in the calibration.
